[33.03] HI Structure of Edge-on Galaxies

J. A. Irwin (Queen's University, Canada)

Aside from the well-known nuclear outflows observed in some
starburst galaxies, edge-on spiral galaxies can also display
considerable activity between the disk and halo far from the
nucleus. HI observations are particularly important for
understanding the kinematics and energetics of these
regions. This talk will focus on the broad scale HI
structure of galaxies in the z direction as well as the
discrete features (sometimes seen as supershells) which span
the disk-halo interface. Infall/outflow scenarios,
energetics, and the possibility of lagging halos will also
be discussed.
